lower sidebar -- change to read:

A variable name must start with a letter, an underscore character,
or a dollar sign. Subsequent characters can be letters, underscores,
dollar signs, or digits. Thus, these are valid variable names:
myCan, Can1, $Can, and _Can1. These are not: 1Can and !Can.

Footnote

The footnote mentions a Dynamic HTML technique covered in Chatper 9, but
it isn't included in Chapter 9. Here it is -

Here's the solution. Replacing each instance of 'window.document.width'
in the script with 'document.body.clientWidth' (note capitalization)
will work in both Netscape 6+ and IE5+.

The exception ie IE6 when in "strict" or "standards compatability"
mode, which is turned on by using a doctype tag like the following:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN">

In this case, rather than returning the width of the client window
minus the scrollbars, document.body.clientWidth returns the width of
the <BODY> element, which, in my tests, amounts to the width of the
client window including the scrollbars. In this instance, use
document.documentElement.clientWidth to get the same value as for all
the other browsers.

Example 8-11

Insert the following line:

var reg = document.forms["reg"];

as the first line after the comment in setValues(), so you have:

// Set cookie values from form data
var reg = document.forms["reg"];
setCookie(reg.yourname.name, reg.yourname.value, exp);

Also, insert the following line:

var reg = document.forms["reg"];

as the first line after the first comment in getValues(), so
you have:

// Get cookie values
var reg = document.forms["reg"];
var namevalue = getCookie(reg.yourname.name);
